SPINNING MACHINE.

Application filed August 11, 1923. Serial No. 656,950.

T @ZZ whom t may concern:

Be it known that I, JOHN G. CI-IAYMAN, a citizen of the United States, residing at Talladega, in the county of Talladega and State of Alabama, have invented new and useful Improvements in Spinning Machines,

' of which the following is a specification.

This invention relatestov spinning machines, and more particularly to amechanism for building a bunch of yarn on the bobbins when the ring rail is first started.

An object of the invention is to provide a mechanism which will cause the ring rail to start off at the bottom of its first stroke very slowly and to continue the slow motion until a bunch of such length as desired has been built, whereupon the mechanism wvill automatically operate to increase the speed of the ringlrail to complete the operation.v

c traverse motion to form the bunch, if desired, for the complete traverse of the ring rail in one direction, the mechanism thereafter operating automatically to traverse the ring rail at its normal speed to wind the yarn.

Referring to the accompanying drawings, wherein'there is shownl one form of the device illustrating the inventive idea :--.v

Fig. 1 isa sectional elevational view, and

Fig. 2 isa detail view.

Referring to the drawings for a morev detailed description, 10 indicates, conventionally, the frame of a spinning machine, in which is mounted the drive shaft 11 having bearings inl brackets 12 mounted .upon the frame and adapted to receive power from any suitable source (not shown) as through a worin `gear 18, althoughl other means could be employed to drivethe shaft.`

A ring rail traverse device, in the present instance al cam, is Vindicated at 14 and is adapted to reciprocate the ring rail through any suitable mechanism `(not shown), such as is well known in the art. It 1sl not thought necessary to show or describe any particular mechanism for connecting the cam to a ring rail since the invention does not relate to the same. Moreover, it will be understood that the Vcam ltis shown merely for the purpose of lillustrating the invention,

. which is not limited in its application specifically to a cam for operating the traverse rail. When the term cam throughout the specification and claims 1s used, it should be interpreted as covering a cam or any device having an equivalent function.

In the present instance the canr is shown as revolubly mounted upon the shaft 11 and is fixed to a sleeve 15 freely mounted upon the shaft and held in position.againstmovement longitudinally'thereof by meansof a collar 16. The sleeve carries a clutch member 17 cooperating with a double faced clutch member 18 keyed to the shaft by means of a key 19 and slidable longitudi-r nally ofthe shaft.V `The clutch member 17 is formed upon a gear 2O fixed to the sleeve 12 and meshing with a gear 21 upon ashaft 22 mounted in bearings 23.l `Another gear 25also secured to the shaft 22, meshes with a gear V26 rotatablewith the drive shaft 11 and held against longitudinal movement thereon by means of collars 27. The gear 26 is formed with ay clutch member 28 cooperating with the slidable clutch member 18 and, obviously, when the latter, is moved into engagement with the clutch member 28 upon the gearI 26 the cam is rotated from the shaft 1-1through the reduction gears-25, 21

and 20.- When the slidable clutch member 18 is in theposition shown in Fig. 1 the cam is rotated directly from the shaft and at a '.higherrate of speedl than vwhen it is operated through the .train of gearing described. f

As'shown in Fig. 1, the mechanismis in its normal operating position for traversingthe ring rail at theusual speed for the winding operation. At the starting, however, the cam lllis rotated through the trainv of gearing described so that it will be operated at a slower speed foi' the building. of the bunch. c y

A The invention contemplates theprovision of automatic means for shifting the clutch member 18 from engagement with the gearing at the `completion of the bunch into engagement-with the clutch face 17. For this purpose a bell crank lever 30 may be fulv crumed at 31, the same having a fork 32 4lever may be positioned to hold the clutch member 18 in engagement with the clutch member 28. For automatically releasing the bell crank to permit the spring 35 to shift the clutch the arm 40 is extended upv wardly and has a finger 40" engaging a cani 44 fixedly mounted upon the drive shaft 1.1 by means of a set screw 45. The arm 40 is held in engagement with the cam 44 by nieans of a spring 47 anchored at 48 to anv adjacent portion of the frame 10. As the drive shaft revolves the cam 44 engages the finger 40 and throws the arm to the right, as viewed in Fig. 2, permitting the sp-ring 35 to lift thelever 30 and shift the t clutch.

It will be observed: thatl by releasing -the set .screw 45 the cam may be adjusted about the shaft 11 in order tol vary the period of rotation of the traverse cam through the reduction gearing. This adjustment will,

of course, alter the length of the bunch vand lpermit the samel to bebuilt up for one complete stroke of the `rail at the slower speed, or for' a portion .of astrolre, as may be desired. The slow motion of the rail cannot exceed a portion of one revolution of the cam which kwill cause the first upward stroke of the rail since thereafter the clutch will be automatically shifted to cause the traversing of the rail at the desired speed directly from the drive shaft'11. When .the traverse cam is operated through the reduction gears its speed will depend upon the ratio of ,theseV gears, which should be .such asto rotate the cani and move the ring rail during this period at a suiiicieiitly'slow rate of speed f toy cause the yarn to bewound substantially.,

horizontally and to be Wound upon itself.

It will be understood that numerous modifications may be made in the structure whichv has been illustrated and `described without departing from the scope of the invention,

which is more definitely defined in the following claims.
